Description

Technical Field

[0001] The present invention relates to the field of vehicle control technology, and in particular to an overcurrent fault restart method, device, equipment, medium and product. Background Art

[0002] At present, new power distribution methods adopted by vehicles include electronic fuse power distribution and high-side drive power distribution. Among them, electronic fuse power distribution has the ability to supply power during the controller sleep period, while high-side drive power distribution cannot supply power during the controller sleep period. Figure 1 This is a schematic diagram of the electrical principle of a power distribution circuit provided in the prior art, such as Figure 1 As shown, the power distribution principle is basically to power the load controller by driving the transistor to open through the driving signal of the power distribution chip, and to monitor the transistor current in real time by monitoring the voltage across the current sampling resistor. Once the current exceeds the overcurrent threshold, the transistor is turned off to protect the transistor.

[0003] However, at present, during the normal operation of the load controller, if a power distribution overcurrent fault occurs, a restart strategy with equal time intervals (e.g., 100ms) is generally used to redistribute power. If the power distribution is restarted at equal intervals and the restart interval is too large, the success rate of power distribution may be too low. If the restart interval is small, the transistor and the load input capacitor may be damaged due to overheating. At the same time, because there is no setting for the entire vehicle condition when restarting the power distribution, the power distribution may cause fluctuations in the voltage of the entire vehicle due to excessive load current, which in turn affects the safety of the entire vehicle. Summary of the invention

[0029] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0030] It is understandable that before using the technical solutions disclosed in the embodiments of the present disclosure, the types, scope of use, usage scenarios, etc. of the personal information involved in the present disclosure should be informed to the user and the user's authorization should be obtained in an appropriate manner in accordance with relevant laws and regulations.

[0031] Figure 2 The flowchart of the first overcurrent fault restart method provided for the implementation of the present invention is as follows. The embodiment of the present invention is applicable to the case of overcurrent fault restart. The method can be executed by the overcurrent fault restart device in the embodiment of the present invention. The device can be implemented in software and / or hardware, such as Figure 2 As shown, the overcurrent fault restart method includes:

[0032] S101. Obtain the overcurrent fault type of the current vehicle.

[0033] Among them, the overcurrent fault type is a transistor protection overcurrent fault or a wiring harness protection overcurrent fault.

[0034] Specifically, the transistor protection overcurrent fault is mainly set for surge current exceeding the maximum current allowed by the transistor. The wiring harness protection overcurrent fault is mainly set for protecting the wiring harness. Among them, the wiring harness can be understood as the line connection conductor such as the wire in the vehicle.

[0035] S102: Determine a current restart state of the vehicle according to the overcurrent fault type.

[0036] Specifically, different overcurrent fault types correspond to different restart conditions. Exemplarily, the restart condition may be that the vehicle is in a running state or the vehicle is in a stationary state. Since the voltage of the entire vehicle grid fluctuates when the vehicle is in a running state or in a stationary state when restarting due to different overcurrent faults, it is necessary to determine whether this fluctuation will affect the safety of the entire vehicle. During the overcurrent fault restart process, the restart state that does not affect the safety of the entire vehicle is determined as a normal state, and the restart state that affects the safety of the entire vehicle is determined as an abnormal state. When the restart state is a normal state, the current vehicle is restarted for an overcurrent fault, thereby avoiding large fluctuations in the voltage of the entire vehicle grid during the overcurrent fault restart process, which may affect the safety of the entire vehicle.

[0037] S103: When the restart state of the current vehicle is a normal state, control the zone controller of the current vehicle to restart the load controller of the current vehicle at a preset time corresponding to the overcurrent fault type according to the overcurrent fault type.

[0038] Specifically, for different overcurrent fault types, different preset times are used to restart the load controller of the current vehicle. That is to say, each overcurrent fault type corresponds to a restart strategy, so that the area controller of the current vehicle can be controlled in a targeted manner to restart the load controller of the current vehicle at the preset time corresponding to the overcurrent fault type, thereby improving the success rate of the overcurrent fault restart.

[0039] It should be noted that, continue to refer to Figure 1 The regional controller includes a power distribution chip, which can output a drive signal to the transistor, and then supply power to the load controller through the transistor. The drive signal can be understood as a signal that controls the transistor to turn on or off.

[0040] The overcurrent fault restart method provided by the embodiment of the present invention can determine whether the overcurrent fault type of the current vehicle belongs to a transistor protection overcurrent fault or a wiring harness protection overcurrent fault by obtaining the overcurrent fault type of the current vehicle. The restart state of the current vehicle is determined according to the overcurrent fault type, so that the area controller of the current vehicle is controlled according to the overcurrent fault type to restart the load controller of the current vehicle at a preset time corresponding to the overcurrent fault type under the condition of vehicle safety. In this way, on the one hand, the power distribution can be restarted according to different overcurrent fault types to improve the success rate of overcurrent fault restart. On the other hand, when performing overcurrent fault restart, the safety of the entire vehicle can be guaranteed.

[0041] Optional, Figure 3 A schematic diagram of a second overcurrent fault restart method provided by an embodiment of the present invention, Figure 3 Based on the above embodiment, the operation of obtaining the overcurrent fault type of the current vehicle is described in detail. Figure 3 As shown, the overcurrent fault restart method includes:

[0042] S201. Obtain an overcurrent in a power distribution circuit of a current vehicle and a duration during which the overcurrent is greater than an overcurrent threshold.

[0043] Specifically, the overcurrent in the power distribution circuit can be sampled through the current sampling resistor, and the duration of the overcurrent being greater than the overcurrent threshold can be sampled.

[0044] S202: When the overcurrent is a first overcurrent and the duration is a first duration, determine that the overcurrent fault type is a transistor protection overcurrent fault.

[0045] Specifically, the transistor protection overcurrent fault is mainly caused by surge current, that is, when the zone controller is in the wake-up initialization stage, the peak current is generated by charging the input capacitor of the load as soon as it is powered on.

[0046] S203: When the overcurrent is a second overcurrent and the duration is a second duration, determine that the overcurrent fault type is a wiring harness protection overcurrent fault; the second overcurrent is less than the first overcurrent, and the second duration is greater than the first duration.

[0047] Specifically, the overcurrent fault type of the current vehicle is determined according to the acquired overcurrent current and duration, so that a targeted overcurrent fault restart strategy can be implemented according to different overcurrent fault types to improve the success rate of overcurrent fault restart.

[0048] S204. Determine the current restart state of the vehicle according to the overcurrent fault type.

[0049] S205. When the restart state of the current vehicle is a normal state, control the zone controller of the current vehicle to restart the load controller of the current vehicle at a preset time corresponding to the overcurrent fault type according to the overcurrent fault type.

[0050] The overcurrent fault restart method provided in the embodiment of the present invention determines the overcurrent fault type of the current vehicle according to the acquired overcurrent current and duration, so as to subsequently implement the overcurrent fault restart strategy in a targeted manner according to different overcurrent fault types, thereby improving the overcurrent fault restart success rate.

[0051] Optional, Figure 4 A schematic diagram of a flow chart of a third overcurrent fault restart method provided in an embodiment of the present invention, Figure 4 Based on the above embodiment, the operation of controlling the regional controller of the current vehicle to restart the load controller of the current vehicle at a preset time corresponding to the overcurrent fault type according to the overcurrent fault type is described in detail, such as Figure 4 As shown, the overcurrent fault restart method includes:

[0052] S301. Obtain the overcurrent fault type of the current vehicle.

[0053] S302: Determine the current restart state of the vehicle according to the overcurrent fault type.

[0054] S303. When the restart state of the current vehicle is normal and the overcurrent fault type is a transistor protection overcurrent fault, the regional controller of the current vehicle is controlled to restart the load controller of the current vehicle within each preset cycle with the time interval between two adjacent restarts as the first preset time; the time interval between two adjacent preset cycles is the second preset time; the second preset time is greater than or equal to the preset cycle.

[0055] Specifically, Figure 5 A schematic diagram of a restart timing corresponding to a transistor protection overcurrent fault provided by an embodiment of the present invention, such as Figure 5 As shown, within each preset period T1, the load controller of the current vehicle is restarted multiple times, and the time interval between two adjacent restarts is a first preset time t1. Figure 6 for Figure 5 Schematic diagram of the corresponding load input capacitor current change, Figure 7 for Figure 5 The schematic diagram of the voltage change on both sides of the input capacitor of the corresponding load is as follows: Figure 6 and Figure 7 As shown, by using a short time interval to redistribute power for the transistor protection overcurrent fault, the input capacitor of the load can be charged successively. When the voltage on both sides of the input capacitor of the load gradually increases, the surge current peak will gradually decrease. When the surge current peak is less than the current limit of the transistor protection overcurrent fault, the purpose of restarting the power distribution can be achieved successfully.

[0056] Furthermore, since too many power distribution times in a short time interval may cause overheating of the transistor and the load input capacitor, a second preset time t2 can be set, that is, a second preset time is set between two adjacent preset cycles to cool the transistor and the load input capacitor, thereby protecting the load hardware.

[0057] It should be noted that when the overcurrent fault restart is not successful within a preset cycle, that is, the surge current peak is still greater than the current limit of the transistor protection overcurrent fault, it is necessary to wait for a second preset time before continuing the overcurrent fault restart within the next preset cycle.

[0058] For example, the preset period T1 may be 10 seconds, the first preset time t1 may be 10 ms, and the first preset time t2 may be 10 seconds or longer.

[0059] S304: When the current restart state of the vehicle is normal and the overcurrent fault type is a harness protection overcurrent fault, the control area controller continuously restarts the load controller with a time interval between two adjacent restarts being a third preset time.

[0060] Specifically, Figure 8 A schematic diagram of a restart timing corresponding to a wiring harness protection overcurrent fault provided by an embodiment of the present invention, such as Figure 8 As shown, since the harness protection overcurrent fault is caused by non-surge current, the time interval between two adjacent restarts can be set as the third preset time t3 to control the regional controller to restart the load controller.

[0061] Exemplarily, the third preset time t3 may be 10 seconds.

[0062] Exemplarily, when the overcurrent fault type is determined to be a transistor protection overcurrent fault, the flag bit of the transistor protection overcurrent fault may be marked as 1, and when the restart is successful, the flag bit of the transistor protection overcurrent fault may be marked as 0. Exemplarily, when the overcurrent fault type is determined to be a harness protection overcurrent fault, the flag bit of the harness protection overcurrent fault may be marked as 1, and when the restart is successful, the flag bit of the harness protection overcurrent fault may be marked as 0.

[0063] The overcurrent fault restart method provided in an embodiment of the present invention controls the zone controller of the current vehicle to restart the load controller of the current vehicle at a preset time corresponding to the overcurrent fault type according to three different overcurrent fault types. In this way, the zone controller can be controlled in a targeted manner to restart the power distribution of the load controller, thereby improving the success rate of overcurrent fault restart.

[0064] Optional, Fig. 9 A schematic flow chart of a fourth overcurrent fault restart method provided in an embodiment of the present invention, Fig. 9 Based on the above embodiment, the operation of determining the restart state of the current vehicle according to the overcurrent fault type is described in detail. Fig. 9 As shown, the overcurrent fault restart method includes:

[0065] S401. Obtain the overcurrent fault type of the current vehicle.

[0066] S402: Obtain operating parameter information of the current vehicle.

[0067] Specifically, the operating parameter information of the current vehicle is obtained so as to determine whether the operating state of the current vehicle meets the restart condition according to the operating parameter information.

[0068] For example, the operating parameter information may include information such as the current vehicle speed and gear position. The embodiment of the present invention does not specifically limit the operating parameter information.

[0069] S403: Determine the current operating state of the vehicle according to the operating parameter information.

[0070] Specifically, when the driving speed is greater than 0, it indicates that the vehicle is in a driving state, and when the driving speed is equal to 0, it indicates that the vehicle is in a stationary state.

[0071] S404: Determine the restart state of the current vehicle according to the current running state of the vehicle and the overcurrent fault type.

[0072] Specifically, whether the current vehicle can perform an overcurrent fault restart is determined by the overcurrent fault type and the current vehicle's operating state. For example, if the overcurrent fault type of the current vehicle is a transistor protection overcurrent fault, and when the vehicle is in a driving state or a stationary state, the fluctuation of the voltage of the entire vehicle grid caused by the overcurrent fault restart is not large, and will not affect the safety performance of the entire vehicle, indicating that the current vehicle's restart state is normal, so the overcurrent fault restart can be performed regardless of whether the vehicle is in a stationary state or a driving state. For example, if the overcurrent fault type of the current vehicle is a transistor protection overcurrent fault, and when the vehicle is in a driving state, the fluctuation of the voltage of the entire vehicle grid caused by the overcurrent fault restart is large, which will affect the safety performance of the entire vehicle, indicating that the current vehicle's restart state is abnormal, and the overcurrent fault restart cannot be performed, otherwise it will affect the safety of the entire vehicle.

[0073] S405. When the restart state of the current vehicle is a normal state, control the zone controller of the current vehicle to restart the load controller of the current vehicle at a preset time corresponding to the overcurrent fault type according to the overcurrent fault type.

[0074] The overcurrent fault restart method provided in the embodiment of the present invention determines the restart state of the current vehicle according to the current operating state of the vehicle and the overcurrent fault type. In this way, it can ensure that under the condition of vehicle safety, the area controller of the current vehicle is controlled according to the overcurrent fault type to restart the load controller of the current vehicle at a preset time corresponding to the overcurrent fault type, thereby ensuring the safety of the entire vehicle when performing an overcurrent fault restart.

[0075] Optionally, the number of times the zone controller of the current vehicle restarts the load controller of the current vehicle at a preset time corresponding to the overcurrent fault type is less than or equal to the preset number of restarts.

[0076] Specifically, the number of restarts performed by the load controller of the current vehicle is less than or equal to the preset number of restarts, so that damage to the load hardware caused by excessive restarts can be prevented.

[0077] Exemplarily, the preset restart number may be 1000 times.

[0078] Optionally, an embodiment of the present invention further provides an overcurrent fault restart device, Fig.10 The present invention is a schematic diagram of the structure of an overcurrent fault restart device provided by an embodiment of the present invention.

[0081] The restart module 300 is used to control the zone controller of the current vehicle to restart the load controller of the current vehicle at a preset time corresponding to the overcurrent fault type according to the overcurrent fault type when the restart state of the current vehicle is a normal state.

[0088] Optionally, the restart module further includes: a first restart unit and a second restart unit.

[0089] The first restart unit is used to control the regional controller of the current vehicle to restart the load controller of the current vehicle within each preset cycle, when the overcurrent fault type is a transistor protection overcurrent fault, with the time interval between two adjacent restarts being the first preset time; the time interval between two adjacent preset cycles is the second preset time; the second preset time is greater than or equal to the preset cycle.

In this way, on the one hand, it can restart according to different overcurrent fault types to improve the success rate of overcurrent fault restart, and on the other hand, it can ensure the safety of the entire vehicle when performing overcurrent fault restart.
